Propane. This is what makes the flame that heats the air in the balloon.
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
Wind !... The balloons are filled with hot air, which causes them to rise. They are then at the mercy f the wind direction.
No, hot air balloons are typically filled with hot air to become buoyant and rise. Helium is an alternative gas used in some balloons, like party balloons or weather balloons, due to its lighter weight than air.
When hot air balloons were first invented, they were mainly used for recreational purposes and entertainment. They were also used for scientific experiments, such as studying the atmosphere and meteorology. Additionally, military forces used hot air balloons for reconnaissance during wars.
There are traditional hot air balloons, special-shaped hot air balloons (such as animals, objects, or characters), and solar-powered hot air balloons that use solar energy to heat the air inside.

Hot air balloons typically use propane gas as a fuel source for the burner that heats the air inside the balloon envelope. The propane is burned to heat the air, which causes the balloon to rise.
Hot air balloons are now mostly used for leisure
Hot air balloons are typically filled with hot air, rather than a gas, in order to make them buoyant and rise in the air. The air inside the balloon is heated by a burner attached to the basket, which causes the balloon to lift off the ground.
No, it is not. "Regular" air is used, and it is heated. Hot air is less dense than cooler air, and it will rise. If hot air is trapped in an envelope, it will give lift to the envelope and an attached payload.
Hot air balloons burn fossil fuels to produce the heat they need to fly. Anything which burns fuel must also release some pollutants. So yes, hot air balloons do pollute. But it should be noted that most burn propane which is a very clean fuel.
Hot air balloons use propane gas as fuel to heat the air inside the envelope, which causes the balloon to rise. The propane burner provides the necessary heat to keep the air inside the balloon hotter than the air outside.
The first use of hot air balloons was in the American Civil War for surveillance of troop movements.
Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The hot air inside a hot air balloon is what allows it to rise and float.
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
Hot air balloons were used to spy on the enemy. They were also used to communicate, send supplies, and drop bombs.
